Are You Missing Out on Free NHS Glasses? Most People Don’t Know They Qualify

Here’s a fact that might surprise you: millions of people in the UK are entitled to help with the cost of their glasses through the NHS and most of them never claim it.

NHS optical vouchers aren’t just for people on very low incomes. The eligibility criteria is broader than most people realise, and the vouchers can be worth up to £215, enough to cover a complete pair of glasses at many retailers, including online.

So before you spend £100 or more on your next pair, it’s worth taking two minutes to check whether you qualify.

What Is an NHS Optical Voucher?

An NHS optical voucher is a document (called a GOS3 form) that your optician gives you if you’re eligible for help with the cost of glasses or contact lenses. It has a set cash value depending on your prescription strength, and you can use it at any optician or eyewear retailer that accepts NHS vouchers both on the high street and online.

The voucher covers part or all of the cost of your glasses. If your chosen frames cost more than the voucher value, you simply pay the difference yourself.

Who Qualifies for an NHS Optical Voucher?

This is where most people are surprised. You may be entitled to a voucher if you are:

• Under 16 years old
• Aged 16, 17 or 18 and in full-time education
• Receiving Universal Credit (and meet the criteria)
• Receiving Income Support
• Receiving Income-based Jobseeker’s Allowance
• Receiving Income-related Employment and Support Allowance
• Receiving Pension Credit Guarantee Credit
• Named on a valid NHS HC2 certificate (full help) or HC3 certificate (partial help)
• A prisoner on leave from prison

You may also get help if you have a complex prescription needing specialist lenses, or if you are a hospital eye service patient.

That’s a much broader list than most people expect. Universal Credit alone covers a significant proportion of working-age adults in the UK many of whom have no idea they’re entitled to help with their glasses.

How Much Is the Voucher Worth?

The voucher value depends on your prescription strength. The stronger your prescription, the higher the value. Current 2026 rates are:

• Voucher A: £42.40 – for prescriptions under +/- 6 dioptres
• Voucher B: £64.20 – for prescriptions between +/- 6 and 9.99 dioptres
• Voucher C: £94.20 – for prescriptions of +/- 10 dioptres or more

Higher value vouchers are also available for complex lenses, prisms, tints and small frames.

To put that in context, a Voucher A worth £42.40 would cover a complete pair of single vision glasses at most online retailers, with money to spare.

Where Can You Use an NHS Voucher?

Most major UK opticians and eyewear retailers accept NHS optical vouchers, including:

• Specsavers
• Vision Express
• Boots Opticians
• Most independent opticians
• Many online retailers including Glasses Direct

When comparing prices, it’s worth checking which retailers accept NHS vouchers before you choose, the difference in what you actually pay can be significant.

How Do You Claim Your NHS Voucher?

The process is straightforward:

Step 1: Get an eye test. Visit any NHS registered optician. If you’re eligible for help with costs, your eye test will be free. The optician will give you a signed prescription and a GOS3 voucher form.

Step 2: Choose your glasses. Use your voucher at any retailer that accepts it. You can use GlassesCompared to find retailers that accept NHS vouchers and compare their prices side by side.

Step 3: Use your voucher. Hand over your GOS3 form when you order. The retailer claims the value back from the NHS, you just pay any difference if the glasses cost more than the voucher value.

Common Questions About NHS Vouchers

How long is my NHS voucher valid for? NHS optical vouchers are valid for 6 months from the date of issue.

What if my glasses cost more than the voucher? You pay the difference. So if your voucher is worth £42.40 and your glasses cost £69, you’d pay £26.60.

Can I use my voucher online? Yes, many online retailers accept NHS vouchers. You’ll need to post your GOS3 form to them after ordering.

Can I use my voucher for sunglasses or contact lenses? Prescription sunglasses yes, in some cases. Contact lenses yes, if they’re prescribed. Non-prescription sunglasses no.

What if I lose or break my glasses? You may be entitled to a repair or replacement voucher (GOS4) if your glasses are lost, broken or need repair due to wear and tear.

Don’t Leave Money on the Table

If there’s any chance you might qualify, it’s absolutely worth checking before your next eye test. The worst that can happen is you find out you don’t qualify and the best is that you get your glasses significantly cheaper or even free.
